Performing an oath on behalf of the deceased after his death

The questioner:
A person says: A man passed away and he had an oath upon him. Do his sons perform this oath on his behalf after his death, given that...?

The Shaykh:
Return, or rather.

The questioner:
He passed away and he had an oath upon him. Yes.

The Shaykh:
Meaning, the expiation for an oath.

The questioner:
It appears to be the performance of an oath. An oath.

The Shaykh:
Yes, he is asking about the expiation. He has an expiation for an oath upon him.

The questioner:
No, this is not what he deserves.

The Shaykh:
If he died and he had an oath upon him, and if he had an expiation for it and did not perform it, then it is forgiven for him. Yes.

The questioner:
They say: We swear on his behalf. Is it permissible for us to swear on his behalf?

The Shaykh:
He had an oath. What kind?

The questioner:
There is no god but Allah.

The Shaykh:
Two cases.

The questioner:
That is the apparent ruling, yes.

The Shaykh:
That is it, the dispute is over. If he died, the party is gone, so the dispute is over, unless he was an agent. Yes.
